I've seen a lot of threads saying we cant downgrade from lollipop to kitkat, bricking, blah blah blah.
But earlier today I downgraded to the Asia Retail 4.4.4 firmware (.xml.zip) and also to the Brazil Retail 4.4.2 firmware (.xml.zip) from Lollipop (brazil soak)....
So I want to know everyone else's experiences, let's get a thread of the known SAFE ways to downgrade.
Also yes, there are other factors that may contribute to a brick, so people who have bricked tell what you've done in order to brick your phone.
I was lead to believe that flashing 4.4.2, or 4.4.4 asia retail, over lollipop would cause a brick...
TL;DR: Let's try clear up some confusion on downgrading the Moto G
I can only confirm for the XT1033 but I am willing to post whats needed.
@plantator gave some useful information "if you try to flash motoboot and gpt it will give you error and can make some troubles, in this link you run only bat file , it flash gpe 4.4.4 without motoboot and gpt , and next step you flash stock and again without motoboot and gpt. As I said i flash 5.0.1 GPE to 4.4.4 GPE and then to 4.4.4 stock"
And yes if you downgrade from Lollipop to Kitkat you WILL have that weird bloody flickering line going through your screen. the only solution i see so far is turning the screen off and on (lock and unlock) once, and itll disappear. but it comes back everytime phone is booted.
It seems the only safe way to downgrade is to make sure no matter what you do, do not install any over the air update for a version starting with 4, or simply just don't OTA from 4.4.2 to 4.4.4. if you need 4.4.4 to upgrade to 5.0.0 then download the 4.4.4 XML.ZIP firmware.
I'll make the assumption that when 5 hits official OTA rollout itll be safe to download through 4.4.4 unless someone can correct me otherwise.
I downgraded my moto xt1032 from BR soak 5.0->GPE Lollipop 5.0.1 to GPE 4.4.4 using this link:
http://forum.xda-developers.com/moto-g/general/guide-xt1033-downgrade-lollipop-5-0-to-t2969729
and next i just flash stock EU 4.4.4 without flashing motoboot and gpt.bin and it is working! remember do not flash motoboot and gpt.bin
so I back to stock retail EU without problems
What was your "safe" way?
Did you just directly flash everything from 4.4.4?
If not, then what exactly did you do?

Bro, when you have downgraded to 4.4.2, the screen still flickering? (like in 4.4.4)
You can go back to 4.4.2 or 4.4.4, just avoid flashing bootloader (motoboot.img) and partitions table (gpt.bin).
But, don't downgrade via OTA! (WiFi/zip) or you'll hard brick your phone.
Don't do this: 5.0-->4.4.2-->4.4.4 (OTA) or the phone will get bricked in the middle of the update process.
Almost all peoples who bricked their devices was ones who flashed 4.4.2 and OTA to 4.4.4 (which makes no sense to me and it's idiotic), most of peoples with other problems simply didn't apply to tutorials and flashed custom recovery after changing to 4.4.4 and trying to push OTA zip. Another are peoples with bootloops after pushing and installing 5.0/5.0.1 which was easily fixed with gpt file.
So just to put together - you can brick device if you will downgrade to 4.4.2 (which made troubles even when there was KK release before lollipop), other problems are just mostly bootloops and connection problems (which can be fixed with flashing gpt file in first case and/or flashing modems for second).
Can you use moto tool to downgrade to 4.4.4
If i make a cwm nandroid backup while in crdroid kitkat, then upgrade to cm12 and return afterwards back to crdroid from backup... Would that be OK?
I've downgraded from GPE 5.0.1 and everything goes right but I want to know, what about logo.bin? Is it safe to flash it? When I turn on the phone it shows the Google logo and the open lock because it was from GPE lollipop, but I didnt dare to flash logo.bin from Moto 4.4.4 firmware, since that file wasnt listed anywhere with the files that were safe to flash...
So is it safe to flash logo.bin? Has anyone succesfully flashed it?
flash logo without problems, it is only bootlogo file nothing more, i downgraded 5.0.1GPE to 4.4.4GPE and than 4.4.4retail
without touching motoboot.img and gpt.bin, do not flash them!

Thanks man! Im not a total noob, it was just a doubt I had.. Thanks!
I have a little question, if i accidentally flash motoboot or gpt, i can't flash again to lollipop then downgrade again? i don't do it, is just in case.
also, i have a XT1032 with 5.01 GPE lollipop, i can downgrade to 4.4.4 without flashing motoboot and gpt then go to stock 4.4.4? thanks!
if you try to flash motoboot and gpt it will give you error and can make some troubles, in this link you run only bat file , it flash gpe 4.4.4 without motoboot and gpt , and next step you flash stock and again without motoboot and gpt. As I said i flash 5.0.1 GPE to 4.4.4 GPE and then to 4.4.4 stock

Your post is the most sensible one for people to use. I honestly have no idea why anyone would flash 4.4.2 unless they don't have the 4.4.4 firmware. What seems to be happening to those that update from 4.4.2 to 4.4.4 OTA and have problems is that the bootloader was upgraded in 5.01 to version 41.18 Have you done the downgrade yourself and did you get the screen flicker issue? I'm running 5.01 GPE on a XT1032 and for the most part see no reason to downgrade. I will however consider flashing the Motorola stock 5.01 firmware once it's released.
Why I downgrade? only to check if it possible in easy way and sure it is. I like Lollipop very much , and back from gpe to stock only for waiting for stock ota when it arrives, not to flash everything when it comes, im ready now for it

Pls answer: did you get the screen line moving/flicker problem after downgrading?
You can't flash OTA if you downgrade, ex: if you downgraded from 5.0 to 4.4.2 and update with ota to 4.4.4 the phone will brick

What if i do like this:
I'm on XT1033 ASIA, convert to 4.4.4 BR, OTA update to soak 5.0 and then 5.0.1. So the bootolader is updated
And if the OTA is already rollout for ASIA version, then i flashed back to asia 4.4.4 retail without flashing motoboot and gpt, then OTA update to lollipop
How?

Then you can flash OTA because you earlier flashed 5.0 soak test, so bootloader will be the same as the rollout OTA...
You can OTA to 5.0 comming from a downgraded 4.4.4 firmware!
I mean, 5.0 to 4.4.2 to OTA 4.4.4 = brick
But 5.0 to 4.4.4 to OTA 5.0 = will work because you have 5.0 bootloader already! :good:

@BobDiaz for the help http://forum.xda-developers.com/moto-g/help/xt1033-revert-5-0-1-gpe-to-5-0-1-t2987477
Alternative procedures:
1 - Going directly from 5.0.1 GPE to 4.4.4 Moto (suggested per @felipeap )
- In bootloader mode, flash gpt.bin file from 5.0.1 Moto. (It can be found in the OTA 5.0.1 Moto zip file)
- Then, flash 4.4.4 Moto (through bootloader mode)

I quite sure that you can do the same process, just replacing the XT1033 stock 4.4.4 rom with the correct one for XT1032.

There is no xt1032 stock 5.0 or 5.0.1 lollipop yet. If you're on the GPE 5.0.1 ,you'll have to wait until Motorola releases a OTA stock update to lollipop for the xt1032 before trying this method. I intend to just wait for the full stock lollipop firmware to be released before considering the idea of flashing back to stock.

If you didn't notice, you will be unzipping the Motorola stock firmware and hence over writing the GPE stock files. The commands are same for both.
which one is best according to u guys GPE 5.0.1 or Motorola android 5.0.1 ?? as me have xt1033 and using GPE 5.0.1 ..

Thank you for the info. I'll add it to the second post as alternative procedure.
I am currently on 4.4.4 and have done the Developer Edition bootloader unlock and rooted. Would like some advice on advantages or disadvantages of upgrading to 5.1.1.
I am on 4.4.4 as well. What guide did you follow to do the bootloader unlock/root? We're you able to do it on 4.4.4? I wasn't sure if I'd have to upgrade to 5.1.1 or not.

My Moto G4 came with Marshmallow installed and I performed an OTA update to Nougat. I then unlocked my bootloader and flashed some custom Nougat ROMs (7.1.2, so newer than the newest official available version). Now I want to get back to stock Nougat so I can relock the bootloader and all that jazz.
As far as I can tell, only Marshmallow firmware images are available so can I safely flash that (I'm thinking "ATHENE_MPJ24.139-23.4_cid50_subsidy-DEFAULT_CFC.zip") and then OTA to Nougat from there or will that cause problems because I already (presumably) have the Nougat bootloader version? I don't want to brick my phone!
Note I'm using a retail United Kingdom XT1622 Moto G4.
Cheers all in advance,
treela
Ah ha! Found this:
https://forum.xda-developers.com/mo...owngrade-nougat-to-marshmallow-t3487201/page5
Got back to stock Marshmallow all OK
flashing back to marshmallow and being able to relock the bootloader after doing the ota wont really work. best bet is to try and find the stock nougat image and flash it.
If i use twrp to flash device back from nougat to lollipop (stock), will be any chance in a future to install original updates (OTA?)
No!
How to do it? I have official Nougat. I've unlocked bootloader and installed twrp.
I've tried twrp, but can not find debloated flash rom. Some of guys are making downgrade with fastboot over youtube, but they downgrade back only previous version of android, for example from nougat to marshmallow, or from marchmallow to lollipop.

What will happen, if i try with fastboot way? Will I brick the phone?
